Really fun after a couple minutes and you understand what is happening. I have one suggestion for drawing the syphons to reshape them based on their surroundings.
for every syphon use a von-nuemman neighborhood with radius 1, so look at left, right, up, down adjacent pieces. Then map pieces to 2, 4, 8, 16; ie. if up is also a syphon add 8, if left is a syphon add 2, for a total of 10. if the total is 10 you make the syphon shape
. using these values allows you to get a unique number for each shape. if the total is 0/(30=2+4+8+16) leave it as the default all four sizes as either all disconnected looking for a connection or connected on all four sizes. I hope this description makes sense its hard to write here and I tried using tables but the formatting on itch doesn't work for a successful visualization.
